Buffer time
Deliberate spacing left between scheduled posts so content doesn't publish back-to-back and overwhelm your audience.
Buffer time is the intentional gap you leave between scheduled posts. Rather than firing several pieces of content in quick succession, you space them out so each has room to breathe, and so your audience isn't flooded by a cluster of posts all at once. The name reflects the idea of a cushion between publishes.
The reasons to build in buffer time are practical. Posting several things in a short window can bury your own content: a post published minutes after another competes with it for the same audience's attention, and the earlier one may barely start distributing before the next appears. Spacing also protects your audience's experience: nobody enjoys a feed suddenly dominated by one account. And from a distribution standpoint, giving each post time to accumulate early engagement independently tends to serve it better than crowding several together.
Buffer time is closely tied to how a scheduling queue is set up. When you define recurring slots (say, one in the morning and one in the evening), the gap between them is your buffer, ensuring posts never stack up even as you batch-fill the queue. It also complements knowing your best times to post: you want each post in a strong window, but not so tightly packed that they cannibalize each other.
How much buffer is right depends on your volume and platform. A few hours between posts is a common baseline for active accounts; lower-frequency posters naturally have wide buffers already. The principle is simply to avoid back-to-back publishing that dilutes each post's chance to perform, and to let your scheduling setup enforce that spacing automatically.
